STORM-SASH HOLDER.

Application filed February 11, 1921.

To all whom it may concern Be it known that I, ARTHUR W. PALM, a subject of the King of Sweden, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Storm-Sash Holders, of which the following is a specification. Y

This invention relates to builders hardware and the object is to provide an improved type of storm sash opener and holder. The invention is fully disclosed in the accompanying drawing, in which:

Figure 1 is a sectional elevation of the lower part of a well known type of window frame and sash construction, showing the inner sash, as shut. Y

Fig. 2 is a reduced fractional view of portion of Fig. 1, showing the sashes open.

Fig. 3 is an enlarged substantially diametrically detail sectional view of the cylinder 4.

Referring to the drawing by reference nu* `1nerals, 5 designates a window frame having an inclined window sill 6 and parting strips 8 and stops 7 and 9, between which slide the inner and outer window sashes 1() and 11, all of common construction. In recess 12 in' the frame 5 is positioned the storm sash 13, the same being hung from its top by suitable hinges (not shown) in the customary way.

My invention is embodied in a device which is coperatively connected to the inner sliding sash 10 and the storm sash 13.`

A bracket 14, having an ear 15, is secured to the outer lower part of said inner sash,

and a similar bracket 16, having an' ear 17', is secured higher up on the inner side'of the storm sash 13. Pivotally secured to the ear 17 is the short arm 18 of an angular plunger rod 19. The plunger rod 19 is provided at its opposite end with a piston 2() slidably mounted in the cylinder 4, said cylinder having an ear 21 at one end pivoted to the ear 15.

Hthin the cylinder 4 are two co-aeting comparatively stiff springs 22 and 23, one on each side of the piston 20. These springs normally hold the piston 2O in the middle Specification of Letters Patent.

Patented Aug. 30, 1921.

Serial No. 444,271.

to hold the piston 20 down and the storm,

sash 13 in. hen it is desired to let air into the room, the sash 10 is raised and the storm sash 13 is automatically pushed out to the position shown in Fig. 2, until the arm 18 f touches the bracket 16, thus preventing the sash from being pulled in again. In case the storm sash sticks because of ice or eX pansion, the spring 23 will permit the sash 10 to be raised sufficiently so that some instrument can be inserted between it and the sill 6 and force the storm sash out by a more direct pressure against its lower strip. The springs 22 and 23 will also act as antirattlers when the sash 13 is extended out and subject to the action of the wind.

It is understood that suitable modifications may be made in this device if such modifications come within the spirit and scope of the appended claims. Having now therefore fully shown and described my invention what I claim to be new and desire to protect by Letters Patent is:

1. In combination with a vertically slidable window sash and a storm sash adapted to be swung outwardly therefrom, a cylinder pivotally connected to one of thesashes, a piston slidably mounted in the cylinder, two springs in said cylinder, one on each side of the piston, and aconnecting rod having said piston at one end and pivotally secured at the other end to the other sash.

2. In combination with a vertically slidable window sash and a storm sash adapted to be swung outwardly therefrom, an opening lever, and means for pivotally connect-V ing one end of the same to one of said sashes and the other end to the otherV sash, said lever being angularly formed near the end attached to the storm sash so as to engage thereagainst when raised to substantially horizontal position.

In testimony whereof I afiix my signature.

. ARTHUR W. PALM.
